SUM(184) adds C units of data beginning with the data in R1 and outputs the
result to D+1 and D. The settings in C+1 determine whether the units are
words or bytes, whether the data is binary (signed or unsigned) or BCD, and
whether to start with the right or left byte of R1 if bytes are being added.
When bit 14 of C+1 has been set to 0, SUM(184) treats the data as binary. In
this case, bit 15 determines whether the data is signed (bit 15 = 1) or
unsigned (bit 15 = 0).
When bit 13 of C+1 has been set to 1, SUM(184) adds bytes of data. In this
case, bit 12 determines whether the calculation starts with the rightmost byte
of R1 (bit 12 = 1) or the leftmost byte of R1 (bit 12 = 0).

Table length
specified in C
The actual table length specified
in C depends upon the units
(words or bytes) set in C+1.
D
Operation
ON if the content of C isn't within the specified range of
0001 through FFFF.
ON if the BCD data has been specified, but the range
contains binary data.
OFF in all other cases.
ON if the result is 0000.
OFF in all other cases.
ON if bit 15 is ON in the result.
OFF in all other cases.
